JOHN M. JORDEN, OF BALTIMORE, MARYLAND.

FIRE-PLUG AND HYDRANT.

Specification of Letters Patent No. 909, dated September 8, 1838.

To all 'whom t may concern:

Be it known that I, JOHN M. JoRDEN, of the city of Baltimore and Stateof Maryland, have invented a new and useful Improvement in Fire-Plugsand Hydra-nts to Prevent the Tater from Freezing in Them; and I d0hereby decla-re that the following is a full and exact description.

In the common way of using plugs and hydrants the water, by remaining inthe pipe above the lower line of the gro-und pipe, they are subject tofreezing and may, `by frost be rendered useless, but if kept in `order,are invaluable in time of fire.

Figure l represents the ordinary fire plug a, a, Vthe screw cap, whichmay be removed to attach hose as they are variously attached. Fig. '2, asection of a plug or hydrant b, a handle to turn off and on the water bythe cock c, below. d, the main or ground pipe, e the upright pipe, f, anose or spout of a hydrant.

In Fig. 3, b, is the handle as seen in Fig. 2, the cross top is fastenedon the stem by a screw, so that it may be taken ott', repaired andregulated. I adjust the cock without taking up the pavement. b, c, is asocket joint with a pin to connect the rod to the screw d, so as toadjust and regulate the cock. e, e, is a brass piece, the bottom of`which is a screw which lits in f, f, which the part f, f, of Fig. 1, andbecomes a sta tionary fixture of the cock. g, is the continuation of thescrew d, through c, e, below g. i, l1., is a brass piece with thewashers on represented by the rod; when the rod b, of which the screw d,and g, and the -piece to which the leathers h, c', are attached isturned to shut off the water, the leather z', shuts down close on to theopening 7c, but when the water is running the leather it, closes ,upunder, in the inside of the'screw e, andcloses a small hole which passesup from the inside to the outside at e, on theright in Figs.V

2 and 8, in nut e, e, of Fig.` 3; it wastes the water which would remaininthe pipe above the cock when the cock is closed, or the water of themain pipe shuts od. Z, is a washer or nut to hold the leather washer onat z'. The leather washers form durable and perfect valves, which metalalone could not do.

Fig. 4 is a wrench to unscrew the piece'V e, e from the part f f torenew the'valves and other purposes.

Fig. 5 represent-s the top view of the piece or nut e, c, with theturning screw or handle (Z, g, taken out. The small hole m, at the sideis the waste hole mentioned in Fig. 3. Hence it may be seen that whenthe Washer c is down and closes the hole R of the pipe and cock, thewater from the pipe at e, in the right passes up past the side of h, c',and past the screw and out at the small hole in the piece at e, at theright hand of the piece c, e.

Vliat I claim is- The particular manner in which I have constructed thecock or plug, for closing or opening the aperture 7:, in combinationwith the screw cap e, with tsopening for discharging the waste water, asabove described.
